Deploying new code which relies on a non-backward-compatible database changes - how do you update the application and the database without any downtime?

What tools and processes do you use for this? Are there any established best practices?

For more context, I'm using a managed SQL database and the application runs on Kubernetes.

I have 6+ years of experience as a data scientist and ML engineer. I'm interested in the software engineering or quantitative developer roles in hedge funds, trading firms and investment banks but it seems like they require previous finance experience or a degree from a top university, often both. I'm getting a 0% callback rate from cold applications.

Any tips for getting interviews? Is it even realistic to target these roles?

Has anyone else noticed this?
